2
00:00:01,306 --> 00:00:03,360
So this is how you open a text file with

3
00:00:03,360 --> 00:00:05,790
your favorite text editor program, and

4
00:00:05,820 --> 00:00:08,010
let me show you how to do the same with

5
00:00:08,010 --> 00:00:10,620
Python. Of course, experience is a

6
00:00:10,620 --> 00:00:13,080
bit different. It's not about double

7
00:00:13,080 --> 00:00:15,510
clicking the file, it's about writing

8
00:00:15,510 --> 00:00:18,210
code. So when you open that file with

9
00:00:18,210 --> 00:00:20,220
your text editor, what happens is that

10
00:00:20,670 --> 00:00:23,520
some object is created in your temporary

11
00:00:23,550 --> 00:00:26,700
memory of your computer, in RAM. So the

12
00:00:26,700 --> 00:00:29,370
file was on the hard disk. When you open

13
00:00:29,370 --> 00:00:32,580
it, it's created as some type of objects

14
00:00:32,580 --> 00:00:35,760
in the RAM. Same thing happens with

15
00:00:35,820 --> 00:00:38,280
Python. In this case, you might want to

16
00:00:38,280 --> 00:00:41,110
store that object, that file object that

17
00:00:41,135 --> 00:00:43,020
that you're going to create in Python, you

18
00:00:43,020 --> 00:00:44,790
might want to store it in a variable.

19
00:00:46,282 --> 00:00:47,543
Let's call it myfile.

20
00:00:49,371 --> 00:00:50,490
The open function

21
00:00:50,520 --> 00:00:54,420
is what creates file objects, and since

22
00:00:54,420 --> 00:00:56,970
it is a function, it will get an

23
00:00:56,970 --> 00:01:02,010
argument. Now, this basics.py file is in

24
00:01:02,010 --> 00:01:06,121
the same directory with the fruits.txt file,

25
00:01:06,145 --> 00:01:08,355
please download the fruits.txt file,

26
00:01:08,379 --> 00:01:09,704
which looks like this,

27
00:01:09,810 --> 00:01:13,590
or let me place it here, you can drag a file on

28
00:01:13,590 --> 00:01:16,140
the side here to have two windows on

29
00:01:16,140 --> 00:01:18,420
Visual Studio Code Editor, and you can

30
00:01:18,420 --> 00:01:21,330
do that even in other editors, I'm sure,

31
00:01:21,750 --> 00:01:24,000
if you're using other editors. So this

32
00:01:24,000 --> 00:01:27,540
file for now, let it be in the same

33
00:01:27,570 --> 00:01:31,740
folder with basics.py. Once you do

34
00:01:31,740 --> 00:01:34,950
that, then the input for this function

35
00:01:35,010 --> 00:01:38,610
is the path to the file. In this case,

36
00:01:38,610 --> 00:01:42,390
that will be fruits.txt. Since the

37
00:01:42,420 --> 00:01:44,040
fruits.txt file is in the

38
00:01:44,040 --> 00:01:48,090
same directory with basics.py. Now to

39
00:01:48,090 --> 00:01:50,610
read the contents of fruits.txt in

40
00:01:50,610 --> 00:01:52,140
your text editor like we did

41
00:01:52,170 --> 00:01:53,880
graphically, it's just about double

42
00:01:53,880 --> 00:01:55,380
clicking the file and then you see the

43
00:01:55,380 --> 00:01:59,100
content on the Text Editor interface. In

44
00:01:59,100 --> 00:02:01,710
Python, things are a bit more, they have

45
00:02:01,710 --> 00:02:04,020
to be a bit more explicit, you have to

46
00:02:04,020 --> 00:02:05,970
specify what you want to do. Because

47
00:02:06,000 --> 00:02:07,860
this file, we have just created a file

48
00:02:07,860 --> 00:02:13,050
object. If we execute that, nothing is

49
00:02:13,050 --> 00:02:16,050
going to happen. An object is going to

50
00:02:16,050 --> 00:02:18,600
be created in temporary memory, and when

51
00:02:18,600 --> 00:02:22,710
the execution of the program ends, the

52
00:02:22,710 --> 00:02:24,900
object will be deleted from the memory,

53
00:02:25,025 --> 00:02:27,155
just like when you open the text

54
00:02:27,180 --> 00:02:28,800
file with the text editor, and then you

55
00:02:28,800 --> 00:02:31,500
close it, the object, the file object is

56
00:02:31,525 --> 00:02:34,105
deleted from RAM, from the temporary memory.

57
00:02:34,535 --> 00:02:36,965
So if you want to read, what you might

58
00:02:36,990 --> 00:02:43,855
want to do is print out myfile. Now myfile

59
00:02:43,879 --> 00:02:47,670
has a read method. So this is the

60
00:02:47,700 --> 00:02:50,130
object, the file object which has a read

61
00:02:50,130 --> 00:02:52,920
method. It doesn't take any arguments.

62
00:02:53,116 --> 00:02:55,426
So just leave it like that, Save,

63
00:02:56,132 --> 00:02:59,610
execute, and here you get the output of

64
00:02:59,610 --> 00:03:03,420
the file. This is how you read a file in Python.
